| Abstract | ||
| Owing to the increasing importance of the Mathematical transformation and in solving various scientific problems, and also the steganography which concept has developed more and more, with its expansion in performing security and Robustness for the digital data for any media and for decreasing the capacity of storage and increasing the speed in transmitting and receiving, in this research, we use the discrete wavelet transform as a comparative study through the hiding methods, which is applied in the time domain. The statistical term MSE is applied which is always used for comparative, and another term MAPE is added as a supporting term and then calculated the PSNR to measure the quality of the images and speeches after reconstruction depending on the two terms. The Colored images are applied because of their high specifications and large area in the storage through hiding processes, which depends on the (LSB) method of hiding. In this research it is methods proposed for designing new coefficients depending on the filters Haar and DB-4, and the design depended on a mathematical method; As an application for the comparative and proposed methods, it depended on a sample of (24) persons. Whose images and speeches were taken to apply the process by hiding speech through the image for every person, and then applied the transformations depending on the proposed Algorithms. The program is designed using Matlab language, and then a comparison is applied between the used methods which showed high quality in reconstruction and performed proposed methods in the security depending on mathematical transform and not only on the methods of ciphering of data through hiding and this method gives a high robustness for data hiding. | ||
